  1. 11. Protective Tribofilms on Combustion Engine Valves

    Author : Robin Elo; Staffan Jacobson; Mikael Åstrand; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Internal combustion engine; valve; sealing surface; tribofilm; oil residue; test rig; Teknisk fysik med inriktning mot tribomaterial; Engineering Science with specialization in Tribo Materials;

    Abstract : Inside the complex machinery of modern heavy-duty engines, the sealing surfaces of the valve and valve seat insert have to endure. Right next to the combustion, temperatures are high and high pressure deforms the components, causing a small relative motion in the interface. READ MORE

  2. 12. Revealing the potential of Nordic microalgae : turning waste streams into resources

    Author : Martin Plöhn; Christiane Funk; Leif J. Jönsson; Maria Barbosa; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Microalgae; Biotechnology; bioremediation; Heavy metal; Biopolymer; Biodegradable; Sustainability; Chlorella vulgaris; Biochemistry; biokemi; environmental science; miljövetenskap;

    Abstract : As the world's population grows, the demand for fresh water, food, fuel, energy and modern technology increases tremendously. Not only does this require enormous amounts of resources but it also increases the amount of waste and especially wastewater. READ MORE

  3. 13. Surface Engineering Approach to Frictional Optimization

    Author : Staffan Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piston Ring; Lubrication; Rig testing; Tribometer; Design of Experiments; Cylinder Liner; Friction; Oil consumption; Diesel Engine; Wear;

    Abstract : Reducing emissions is a top priority within heavy duty diesel engine development and research. The power cylinder system is a main contributor to emissions and accounts for about 50% of the total frictional losses found in the engine, so is important to optimize. READ MORE

  4. 14. Engine Optimized Turbine Design

    Author : Nicholas Anton; Anders Christiansen-Erlandsson; Magnus Genrup; Marc Gugau; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbocharger; Heavy-duty; Turbine; Axial; Radial; Machine Design; Maskinkonstruktion;

    Abstract : The focus on our environment has never been as great as it is today. The impact of global warming and emissions from combustion processes become increasingly more evident with growing concerns among the world’s inhabitants. The consequences of extreme weather events, rising sea levels, urban air quality, etc. READ MORE

  5. 15. Experimental evaluation of renewable drop-in fuel blends for compression ignition engines

    Author : Josefine Preuss; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Compression Ignition Engine; Renewable fuels; Particle emissions; long-chain alcohol blends;

    Abstract : Driven by the need to reduce greenhouse gas emissions while meeting the growing demand for mobility, the transport sector is shifting towards more sustainable and less polluting energy sources. Although vehicle electrification is advancing, it will take decades for electric vehicles to completely replace all current vehicles powered by internal combustion engines. READ MORE
